I make a living solving crimes.

The crime scene was a courtyard house with three families living in it. When the police from the police station arrived, the owner of the house had already been injured and unconscious and was sent to the hospital.

There were people inside and outside the yard. The neighborhood committee's security committee members were trying their best to maintain order, but they still couldn't stop the people from coming to watch the fun.

Zhang Youde led the police into the yard, looked at the mess, frowned and shouted, "Let's see if those who want to enter the crime scene are accomplices of the criminals."

Good man, he starts to put labels on people right away.

The crowd dispersed.

From the yamen runners and constables in the feudal era, to the police patrols in the previous dynasty, to the public security police in the new era, there is no one that the common people are not afraid of.

"If you don't obey me, I will let the police take you away."

All children born two thousand years ago have heard this.

Later, civilized law enforcement began and the people began to live in harmony with the police. Only then did some people dare to act like a scoundrel in front of the police.

I don’t know whether this is progress or regression.

The public security committee member came over to report the situation. The injured person was named Zheng Zhongtian, a 40-year-old man, and the original owner of this courtyard house. After the state took over the management of the idle houses, the rooms on both sides were divided out. Zheng Zhongtian did not have a job and was usually a low-key person, with no major conflicts with his neighbors.

There were no witnesses at the scene and no one heard the noise. Zheng Zhongtian was discovered when his wife came back from buying groceries. They called the neighbors in to help carry the person to the hospital. There were very obvious signs of a search in the bedroom to the east of the main house. In addition, people were trying to rescue people at the time, and it is possible that someone wanted to take advantage of the situation. The scene was completely destroyed.

There was a splatter of blood on the wall, probably caused by a blunt object hitting the brain. The victim looked to be in serious condition.

Chang Wei had followed his father to the scene since he was a child, so he knew better than Li Lai Fu where to stand so as not to get in the way. He found a deserted spot, squatted there, and watched Li Lai Fu being ordered around with a cigarette in his mouth.

In the past two years, three young policemen have joined the police station. Who else should we use if not them?

He came out of his corner only after the first wave of sampling and evidence collection was completed. At this time, the police began to look for witnesses and the public to conduct a survey, and no one cared about him, so he wandered around on his own.

The ground was covered with footprints. Ever since the system awarded him the ability to identify footprints, Chang Wei could already tell a lot from them. With a rough calculation, he could tell the height and body shape of the owners of these footprints.

But footprint identification is ultimately not reliable. Chang Wei felt that he was foolish to try to find the murderer's footprints in such a complicated environment.

He stood in front of the house for a long time, slapped his head, and tried to combine the footprint identification with the all-seeing eye.

The exploding pain stimulated his eyes, and when he opened them again, the world in front of Chang Wei had changed as if he were in a game world. Every footprint on the ground had a cursor guide and detailed analysis.

"Male, height 168cm, weight 61kg, age 30-35, cloth shoes."

"Male, height 173cm, weight 66kg, age 40-45, leather shoes, military training."

"Female, height 159cm, weight 49kg, age 20-25, cloth shoes, walks with feet turned inward."

"..."

"..."

Chang Wei staggered out of the crime scene with complicated clues, and followed two sets of footprints to the patio between the main house and the east wing.

After Zhang Youde finished talking to the security committee member, he saw Chang Wei's leisurely appearance, walked over and patted his shoulder and said, "The case is a bit complicated, so we have to eat later today."

Chang Wei was dizzy after watching for just over ten minutes. He quickly separated the footprint identification from the all-seeing eye, and his mind gradually became clear. He chuckled and said, "Is it an acquaintance who committed the crime?"

Zhang Youde said "Yo", took out a cigarette, lit it and asked in a thoughtful manner: "How did you know that?"

Chang Wei walked to the door and pointed at the padlock, "This was unlocked to get in. There are no signs of the doors and windows being pried open."

Zhang Youde nodded without comment and said, "Not enough, continue."

Chang Wei walked into the east bedroom, stood at the location of the bloodstain and said, "The security committee member just said that Zheng something, um, the victim, was injured in the back of the head."

Li Laifu, who was still searching for evidence in the room, looked confused and asked, "What does this have to do with someone you know committing a crime?"

Chang Wei looked at the young policeman who was three years older than him with disdain. He pulled his collar and asked him to stand at the bloodstain and said, "There is no place to hide inside. The victim must have discovered the suspect. He did not call for help from the neighbors, but was ambushed when he was leading the suspect outside."

Li Lai Fu stood there in confusion, and it took a while for him to show an expression of sudden enlightenment.

Chang Wei nodded with a teachable look, then led the two of them out of the house, walked to the patio, and looked back.

Everyone stand back, I'm going to start pretending to be... a saint.

There were also many footprints here. Chang Wei found a dry branch nearby and pointed at a few overlapping footprints and said, "The suspect is 40 meters tall, weighs kilograms, is a male, wears cloth shoes, is about years old, has received simple military training, has an injury to his right leg, and walks with a slight limp."

Then he pointed to another footprint with the toes pointing in opposite directions and said, "This is from the same person, but it weighs 72 kilograms, which means that when he left, he was carrying more than 20 kilograms of weight."

The scene fell into silence for a moment, and the six policemen, including Zhang Youde, looked at him without saying a word.

Chang Wei's nostrils were pointed upwards.

Zhang Youde went up and patted the guy on the head, and asked in confusion: "Did you tell from the shoe prints?"

Chang Wei rubbed the back of his head with his eyes wide open, raised his neck and said: "I am from Longhu Mountain..."

Zhang Youde was not willing to indulge him, so he kicked him on the butt and shouted, "Speak properly."

Chang Wei stiffened his neck and refused to accept the defeat. How could a great detective like him be kicked in the ass by someone so casually? He pulled Li Laifu viciously and said, "Go to the hospital by bike and ask the family if there is such a person, who is 1.7 meters tall, weighs 60 kilograms, has a slight limp in his right leg, and is very familiar with his family."

Li Laifu stupidly didn't even ask why you assigned me. He glanced at Zhang Youde's face, asked Wu Jimao, a young policeman of the same period, and rode his bicycle to the hospital.

After the apprentice left, Xiao Qiang walked up and asked curiously, "Did you really tell from the footprints?"

Chang Wei smiled and said, "Uncle Xiao, tell me two stories about fighting foreign devils, and I will tell you how to count footprints."

The more Xiao Qiang looked at him, the more he liked him. He turned to Zhang Youde and said, "Director, why don't we just change apprentices? Lai Fu is much more diligent than this kid."

Zhang Youde glanced at him and turned away.

Almost an hour later, Wu Jimao rushed back on his bike and started shouting before he even entered the yard: "We caught him, we caught him."

The police in the yard were still writing down Chang Wei's height formula and weight formula on paper. When they heard the voice, they walked out quickly and asked, "What did you catch? Is it a criminal?"

Wu Jimao parked the car, found Chang Wei in the crowd, looked at him admiringly and said, "Chang Wei, you are really capable."

Xiao Qiang came over and asked curiously: "How did you find it?"

"When we went to the hospital to ask, Zheng Zhongtian's wife said it must be Wu Dinghai. The instructor immediately took them to arrest him. As soon as we entered the yard, Wu Dinghai saw us and ran away, but was held down by Li Laifu."

"Are you sure it's him?"

"No doubt about it. He is 1.7 meters tall and weighs about 120 kilograms. He has short legs. We also found a bloody crowbar and a bronze gui weighing about 20 kilograms in his room."

"hiss!"

Everyone in the yard looked at Chang Wei as if they were seeing something strange. Zhang Youde had a subtle expression on his face and patted Chang Wei's shoulder vigorously, "You are such a good boy! Who did you learn this from?"

Chang Wei has a proud little face.
